Fig. 1 is a diagram illustrating an architecture of an information processing system according to an embodiment of the present invention, where an information processing method according to an embodiment of the present invention is implemented based on the architecture of the information processing system. An information processing system 1 in an embodiment of the present invention includes: a first terminal 2, a network function virtualization network 3 and a second terminal 4. The network function virtualization network 3 at least comprises a service application server 301 and a virtual call session control function network element 302, and a communication connection is established between the service application server 301 and the virtual call session control function network element 302; the first terminal 2 and the second terminal 4 respectively establish communication connection with the network function virtualization network 3, and when the first terminal 2 and the second terminal 4 perform data interaction through the network function virtualization network 3, the service application server 301 and the virtual call session control function network element 302 also perform data interaction to execute the information processing method provided by the embodiment of the invention.

The following embodiments are all implemented based on the system architecture of fig. 1.

Example one

An embodiment of the present invention provides an information processing method, which is applied to a service application server, and fig. 2 is a flowchart illustrating an implementation of the information processing method according to the embodiment of the present invention, where as shown in fig. 2, the data index analysis method includes:

s101, in a network function virtualization network, when call connection is successfully established, service triggering information sent by a virtual call session control function network element is received.

In the embodiment of the invention, the information processing method is applied to a network function virtualization network, and a service application server and a virtual call session control function network element in the network function virtualization network carry out data interaction so as to realize Internet access service guidance based on VoLTE voice communication; firstly, when the call connection between the calling terminal and the called terminal is successfully established, the service application server can receive the service triggering information sent by the virtual call session control function network element.

It should be noted that before the calling terminal and the called terminal perform the VoLTE voice call, a call connection needs to be established between the calling terminal and the called terminal, and when the call is successfully established, that is, when the VoLTE voice call can be performed between the calling terminal and the called terminal. In addition, the service application server and a virtual call Session Control Function network element vS-CSCF (virtual call Session Control Function) both belong to network elements in the network Function virtualization network, and the service application server is a special network element which is newly added in the network Function virtualization network and is used for determining information carrying a network link address according to service trigger information; the service triggering information is used for triggering the service application server to generate information carrying the internet access link address, and the information is used for guiding the terminal to access the network, so that the guidance of the internet access service is realized.

In the embodiment of the present invention, a Network Function Virtualization (NFV) Network is an NFV Network, where the NFV Network at least includes a vpec (Virtual Evolved packet core) Network and a vmms (Virtual IP Multimedia Subsystem, IP (internet protocol, protocol for interconnection between networks)) Network.

Fig. 3 is a schematic diagram of a framework of an NFV network according to an embodiment of the present invention, as shown in fig. 3, the NFV network includes an NFVI module, a VNF module, and a MANO module; the NFVI module comprises a hardware resource pool and a virtualized resource pool cloud operating system, wherein the hardware resource pool comprises virtual computing resources, virtual storage resources, virtual network resources and the like, and the cloud operating system comprises a virtualized management program and a related management module; the VNF module includes a virtualized network element (e.g., a vppc network element, a ims network element, etc.) and a network element management module, and is configured to deploy a Virtual network function on a cloud operating system in the NFVI network to implement the vppc network element and the ims network element function, for example, the vppc network includes logical network elements such as a vme, a vS-GW (Virtual serving gateway), etc., and the vsims network includes logical network elements such as a vS-CSCF, a service application server, etc.; the MANO module comprises three entities of Virtualized Infrastructure Management (VIM), Virtual Network Function Management (VNFM) and Network Function Virtualization Orchestration (NFVO), and manages NFVI, VNF and network service objects respectively.

It can be understood that in the NFV network, the software processing of the corresponding function is carried by using the general hardware and the virtualization technology, so that the expensive equipment cost of the network is reduced; meanwhile, by software and hardware decoupling and function abstraction, the functions of the network equipment do not depend on special hardware any more, resources can be fully and flexibly shared, rapid development and deployment of new services are realized, and automatic deployment, elastic expansion, fault isolation, self-healing and the like based on actual service requirements are realized.

And S102, acquiring information carrying the internet access link address from a local database according to the service triggering information.

In the embodiment of the invention, the service application server is provided with a local database for storing the internet access connection address corresponding to the terminal, and after receiving the service trigger information, the service application server acquires the information carrying the internet access link address from the local database according to the service trigger information.

It should be noted that a preset trigger condition is set in the service application server, and when the service trigger information satisfies the preset trigger condition, the service application server is triggered to acquire information carrying the internet access link address corresponding to the service trigger information from the local database.

Further, when the virtual call session control function network element belongs to the calling side, the service application server in S102 acquires information carrying the internet access link address from the local database according to the service trigger information, which specifically includes: when the service triggering information is the identification of the calling terminal and the identification of the called terminal, the service application server determines the corresponding relation between the identification and the information from a local database according to the identification of the calling terminal; and determining the information carrying the internet access link address from the corresponding relation between the identification and the information according to the identification of the called terminal.

In addition, further, when the virtual call session control function network element belongs to the called side, the service application server in S102 acquires information carrying the internet access link address from the local database according to the service trigger information, which specifically includes: when the service triggering information is the identification of the calling terminal and the identification of the called terminal, the service application server determines the corresponding relation between the identification and the information from the local database according to the identification of the called terminal; and determining the information carrying the internet access link address from the corresponding relation between the identification and the information according to the identification of the calling terminal.

That is to say, the service application server adopts different ways of acquiring information carrying the internet link address according to different terminal sides where the sender virtual call session control function network element of the service trigger message is located.

S103, sending the information carrying the internet link address to the virtual call session control function network element so that the virtual call session control function network element sends the information to the opposite terminal to realize internet guiding service.

In the embodiment of the invention, after obtaining the information carrying the internet link address, the service application server sends the information carrying the internet link address to the virtual call session control function network element sending the service trigger information, so that the virtual call session control function network element sends the information to the opposite terminal, thereby realizing the internet guiding service.

It should be noted that the opposite end refers to an opposite end on the side where the virtual call session control function network element is located. For example, when the virtual call session control function network element is a network element of a calling side, the opposite terminal is a called terminal, that is, the information is sent to the called terminal; when the virtual call session control function network element is the network element of the called side, the opposite side is the calling terminal, that is, the information is sent to the calling terminal.

Here, after receiving the message, the opposite end triggers the internet service by clicking the internet link address in the message during the call or after the call is finished.

Further, in this embodiment of the present invention, before the service application server receives the service trigger information sent by the virtual call session control function network element in S101, the information processing method further includes: the service application server receives third party registration information sent by a virtual call session control function network element; generating service authentication information according to the third party registration information; and sending the service authentication information to a virtual call session control function network element.

Correspondingly, the service application server receives the service triggering information sent by the virtual call session control function network element, and specifically includes: and when the service authentication information represents that the authentication is successful, receiving service triggering information sent by the virtual call session control function network element.

Exemplarily, in the NFV network, a terminal a presets a push link corresponding to a terminal B in a database in a service application server AS1 in advance, and when a call connection between the terminal a and the terminal B is successfully established, an AS1 receives service trigger information including an identifier of the terminal a and an identifier of the terminal B sent by a virtual call session control function network element on a terminal a side; at this time, the AS1 obtains the corresponding relationship between the identifier and the information from the local database according to the identifier of the terminal a in the service triggering information; the AS1 further acquires link information matched with the identifier of the terminal B from the corresponding relation between the identifier and the information, and generates a link short message (carrying information of an internet link address) according to the link information; the AS1 sends the link short message to the terminal B through the virtual call session control function network element; and the terminal B accesses the network according to the link address in the link short message.

It can be understood that, in the network function virtualization-based internet service guiding method provided in the embodiment of the present invention, the internet service guiding service is implemented based on the NFV network, and the implemented vpec/vmms core network element function and the traditional service capabilities of VOLTE call, internet access, and the like are applicable to NFV technology network evolution and 5GC service development; meanwhile, the information processing method takes the traditional VoLTE voice and short message service as a new entrance of the internet service, thereby increasing the operation income of the internet service, being also taken as a propaganda highlight of the VoLTE service and highlighting the technical advantages of the VoLTE and NFV networks.

It can be understood that, after the newly added service application server receives the service trigger information sent by the virtual call session control function network element, the newly added service application server obtains the information carrying the internet link address from the local database according to the service trigger information, and sends the information to the opposite end through the virtual call session control function network element, thereby implementing the internet guidance service in the network function virtualization network, and widening the application range of the internet service.

Example two

An embodiment of the present invention provides an information processing method, which is applied to a virtual call session control function network element, fig. 4 is a flowchart illustrating another implementation of the information processing method according to the embodiment of the present invention, and as shown in fig. 4, the data index analysis method includes:

s201, in the network function virtualization network, when call connection is successfully established, service triggering information is sent to a service application server.

In the embodiment of the invention, the information processing method is applied to a network function virtualization network, and a virtual call session control function network element and a service application server in the network function virtualization network carry out data interaction so as to realize Internet access service guidance based on VoLET voice call; firstly, when the call connection between the calling terminal and the called terminal is successfully established, the virtual call session control function network element can send service triggering information to the service application server.

It should be noted that before the calling terminal and the called terminal perform the VoLTE voice call, a call connection needs to be established between the calling terminal and the called terminal, and when the call is successfully established, that is, when the VoLTE voice call can be performed between the calling terminal and the called terminal. In addition, the virtual call session control function network element vS-CSCF and the service application server both belong to network elements in the network function virtualization network, and the service application server is a special network element which is newly added in the network function virtualization network and used for determining information carrying a network link address according to service trigger information; the service triggering information is used for triggering the service application server to generate information carrying the internet access link address, and the information is used for guiding the terminal to access the network, so that the guidance of the internet access service is realized.

It should be further noted that the virtual call session control function network element is divided into a virtual call session control function network element on the calling side and a virtual call session control function network element on the called side.

In the embodiment of the present invention, the network function virtualization network is an NFV network, and the NFV network includes at least a vEPC network and a ims network. The specific NFV network architecture is shown in fig. 3, which has been described in detail in the first embodiment, and the details of the embodiment of the present invention are not repeated herein.

S202, receiving information which is sent by the service application server according to the service triggering information and carries the internet access link address.

In the embodiment of the present invention, after the virtual call session control function network element sends the service trigger information to the service application server, the information carrying the internet access link address sent by the service application server according to the service trigger information is received.

It should be noted that the information carrying the internet link address refers to a short message containing the internet link address.

And S203, sending the information carrying the internet link address to the opposite terminal to realize the internet guiding service.

In the embodiment of the invention, after receiving the information carrying the internet link address sent by the service application server, the virtual call session control function network element sends the information to the opposite terminal, thereby realizing the internet guiding service.

Here, the virtual call session control function network element sends the information to the opposite terminal through the short message gateway; after receiving the message, the opposite terminal triggers the internet service by clicking the internet link address in the message during the call or after the call is finished.

Further, in this embodiment of the present invention, before the network element with a virtual call session control function sends the service trigger information to the service application server, the information processing method further includes: the virtual call session control function network element sends third party registration information to the service application server; and receiving service authentication information sent by the service application server according to the third party registration information.

Correspondingly, the virtual call session control function network element sends service triggering information to the service application server, and the method specifically includes: and when the service authentication information represents that the authentication is successful, the virtual call session control function network element sends service triggering information to the service application server.

It can be understood that, after the virtual call session control function network element sends the service trigger information to the newly added service application server, the virtual call session control function network element receives the information carrying the internet access link address, which is returned by the service application server, obtained from the local database according to the service trigger information, and sends the information to the opposite end, thereby implementing an internet access guiding service in the network function virtualization network, and widening the application range of the internet access service.

EXAMPLE III

Fig. 5 is a flowchart illustrating another information processing method according to an embodiment of the present invention, where as shown in fig. 5, the data index analysis method includes:

s301, in the network function virtualization network, when the call connection is successfully established, the virtual call session control function network element sends service triggering information to the service application server.

It should be noted that the description of the implementation process of S301 is consistent with the description of the implementation process of S201 in the second embodiment, and details of this implementation process are not repeated in this embodiment of the present invention.

S302, the service application server obtains information carrying the internet access link address from the local database according to the service trigger information.

It should be noted that the description of the implementation process of S302 is consistent with the description of the implementation process of S102 in the first embodiment, and details of this implementation are not repeated in this embodiment of the present invention.

And S303, the service application server sends the information carrying the internet link address to the opposite terminal through the virtual call session control function network element.

S304, the opposite terminal accesses the network according to the information carrying the internet link address, and internet guide service is realized.

It should be noted that the description of the implementation process of S303 to S304 is consistent with the description of the implementation process of S103 in the first embodiment, and details of this implementation are not repeated in this embodiment of the present invention.

Further, in the embodiment of the present invention, before the call connection between the calling terminal and the called terminal is successfully established, the information processing method further includes: network element deployment and network registration.

First, network element deployment refers to a virtualized network function VNF that implements a vEPC and a voims in an NFV network environment. It should be noted that, before the network element is deployed, corresponding data packets (such as a mirror image packet, a service version packet, a description file, a policy file, a verification file, a configuration file, and the like) need to be uploaded to the NFVO, and the NFVO uploads the data packets to the VIM, so as to implement the automatic deployment of the network element.

Exemplarily, fig. 6 is a schematic diagram of an exemplary VNF deployment flow provided in an embodiment of the present invention, as shown in fig. 6:

s401, an operator sends an instantiation VNF request to the NFVO. Here an operator such as an operator in an operation support system;

s402, the NFVO validates the instantiation VNF request. For example, the NFVO checks whether the sender of the instantiated VNF request, i.e. the operator, has the right to initialize the VNF instance contained in the instantiated VNF request, and checks the validity of the parameters of the instantiated VNF request.

And S403, when the verification is passed, the NFVO sends an instantiation VNF request to a VNFM which is managed by the VNF. The operator initializes the VNF instance, so that the instantiation VNF request carries parameter information such as a VNF identifier, a VNF instantiation description, and a corresponding VNFD (Virtualized Network Function Descriptor); and the VNFD is a configuration template that describes the deployment and operational behavior of a virtualized network function module.

S404, the VNFM parses the VNFD in the VNF instantiation request, obtains resources (including virtual computing resources, virtual storage resources, and the like) required by the VNF instance, and sends an authorization request of the resources required by the VNF instance to the NFVO. Specifically, the VNFM uses a resource authorization interface to request from the NFVO resource authorization required by the VNF instance.

S405, the NFVO returns resource authorization information to the VNFM according to the authorization request. Specifically, the NFVO checks available resources according to the global resource data, selects a suitable VIM as a resource required by the VNF instance, completes resource authorization, and returns a VIM identifier corresponding to the suitable VIM to the VNFM, that is, the resource authorization information includes information corresponding to the resource that can be used by the VNF instance.

S406, the VNFM sends the virtual machine creating instruction to the corresponding VIM for resource allocation according to the resource authorization information.

And S407, the corresponding VIM establishes the virtual machine according to the virtual machine establishing instruction to obtain a resource allocation result. Specifically, the corresponding VIM allocates resources and notifies the virtualization hypervisor to create a corresponding virtual machine, and joins the created virtual machine to the created network.

And S408, the corresponding VIM sends the resource allocation result to the VNFM.

And S409, deploying configuration of the relevant parameters by the VNFM according to the resource allocation result to obtain a parameter configuration result.

S410, the VNFM sends the parameter configuration result to an EMS (Element Management System). That is, the VNFM notifies the EMS after completing the deployment-related parameter configuration.

S411, the EMS adds the corresponding VNF as a manageable object according to the parameter configuration result.

S412, the EMS configures the network element application related parameters for the VNF, and returns a configuration result to the VNFM.

And S413, the VNFM checks whether the VNF can provide services or not according to the configuration result, and obtains a VNF instantiation result.

S414, the VNFM sends the VNF instantiation result to the NFVO. The VNF instantiation result carries VNF instance identification, virtualized resources occupied by the VNF, and the like.

And S415, the NFVO forwards the VNF instantiation result to an operator to complete network element deployment.

Second, network registration refers to a process in which terminals (including a calling terminal and a called terminal) register with a network function virtualization network. The method specifically comprises registration of a vEPC network and registration of a vIMS network, wherein the registration of the vEPC network comprises a data channel default bearer establishment process and a vIMS default bearer establishment process.

When the terminal is started or visits the network for the first time, the vEPC network needs to be registered, and the vEPC network attachment is completed. Fig. 7 is a schematic diagram of a registration process of an exemplary vEPC network according to an embodiment of the present invention, as shown in fig. 7: the vmmme (Virtual Mobility Management Entity) reports the network VoLTE support capability to the vhs (Virtual Home Subscriber Server) during location update. After the vpec Network is attached, the vmmme initiates a request for establishing a default bearer of a CMNET (China Mobile internet) APN Data channel (APN ═ CMNET, QCI ═ 9) to the vSAE-GW (Virtual Serving Gateway-Packet Data Gateway), and completes establishment of the default bearer of the Data channel, and at this time, the user can access the internet. In addition, the terminal identifies that the network supports VoLTE, and initiates a ims APN default bearer establishment request (APN ═ vmims, QCI ═ 5) to the network after the data channel default bearer is established, at this time, the procedure of establishing the ims default bearer is completed, and at this time, the PDN-GW/SAE-GW returns the IP address of the SBC/vP-CSCF, that is, the entrance address of the ims domain to the terminal according to the SBC dynamic selection policy. The specific process is as follows:

s501, the terminal UE sends an Attach Request (Attach Request) to the vmmme.

S502-S503, the vmmme sends an AIR (Authentication Request) message to the converged vHSS, and receives an aia (Authentication ack) message returned by the converged vHSS in response to the AIR message.

S504-S505, the vMME sends an Authentication Request message to the UE according to the AIA message, and receives an Authentication Response message returned by the UE in Response to the Authentication Request message.

S506-S507, the vMME sends a Location Update Request (Update Location Request) message to the converged vHSS according to the Authentication Response message, and receives a Location Update Response (Update Location Ack) message returned by the converged vHSS in Response to the Location Update Request.

And S508, the vMME sends a Create Session Request message to the vS/P-GW according to the location update response message.

S509-S510, the vS/P-GW sends a CCR (Credit Control Request) message to a PCRF (Policy and Charging rules function) according to the create bearer Request message, and receives a CCA (Credit Control Ack) message returned by the PCRF in response to the CCR message.

And S511, the vS/P-GW sends a Create Session Response message to the vMME according to the CCA message.

S512, the vMME sends an Attach Accept message to the UE according to the Create Session Response message, and completes the default bearer establishment of the data channel.

S513, the UE sends a PDN Connectivity Request message to the vMME according to the Attach Accept message.

Further, in the embodiment of the present invention, after the call connection of the terminal is successfully established, a short message flow is further included, that is, the flow of the information processing method provided in the embodiment of the present invention is included. After the VOLTE called user sends 200ok (invite) off-hook message, at this time, the vS-CSCF triggers the internet access guiding service, the internet access guiding service AS (service application server) calls the content of the internet link in the internal database to generate a link short message according to the information such AS the calling and called numbers AS the judgment condition, the link short message refers to a website connection address which is established on the mobile internet and is specially used for browsing the internet by the mobile phone and is added to the common short message, that is, the information carrying the internet access link address in the embodiment of the present invention. And forwarding the link short message to an opposite terminal user between the VoLTE users through the vS-CSCF and the IP-SM-GW short message gateway, and pushing the link short message to a standard short message process of the same network.

Fig. 10 is a schematic diagram of an exemplary information pushing flow provided by an embodiment of the present invention, as shown in fig. 10: in S801-S805, a VoLTE called subscriber (ue b) sends an ACK/200OK message to a calling subscriber (ue a) to establish a VoLTE call, and then a calling-called vS-CSCF triggers an internet guidance service AS (service application server), which calls the internet link content in an internal database according to the information (service trigger information) such AS the calling number and the called number AS a judgment condition, generates a link short message (information carrying an internet link address), and returns the link short message to the vS-CSCF. And the transmitting terminal vS-CSCF transmits the link short message to the transmitting terminal IP-SM-GW, and the link short message is transmitted to a short message center (SMSC) through a signaling network. And the short message center inquires short message routing information from the three-fused vHSS to which the opposite terminal user belongs. And the HSS of the opposite terminal user attribution forwards the short message routing request message to the receiving terminal IP-SM-GW, and the receiving terminal IP-SM-GW asks the HSS of the opposite terminal user attribution for the short message routing information of the receiving terminal user and then returns the short message routing information to the short message center to indicate the short message center to send the MT short message to the IP-SM-GW of the opposite terminal. And the IP-SM-GW of the opposite terminal sends the link short message to the opposite terminal after receiving the MT short message.

Further, in the embodiment of the present invention, after the opposite terminal receives the information carrying the internet link address, after the call is established, the VoLTE calling terminal (or the called terminal) receives the link short message sent by the opposite terminal, and then the internet link in the short message can be clicked to trigger the internet service during the call or after the call is finished, and the subsequent internet service flow is a standard flow.

Fig. 11 is a schematic diagram of an exemplary internet access flow provided by an embodiment of the present invention, and as shown in fig. 11, a user in a VOLTE call receives a short message containing an internet access link sent by an opposite end, and can select to click the link to trigger an internet access service. In S901-S904, after the VOLTE user terminal identifies the internet link or inputs the URL address of the internet link in the browser, the UE will access HTTP SERVER. Because the UE establishes the default bearer of the data channel after the vEPC network is successfully attached, the UE sends a DNS Query message carrying the URL to the DNS, and receives a DNS Response message carrying the IP corresponding to the URL returned by the DNS according to the DNS Query message, namely the UE constructs the DNS Query message and queries the host IP corresponding to the URL of the WEB site to be accessed. After the UE obtains the WEB site IP, the UE constructs an IP message, transmits the message to vP-GW/vGGSN through a data bearing channel, and then routes the IP packet to the WEB site, wherein GET URL and RESPONSE refer to application layer messages which are packaged in the IP message for transmission.
